    Abstract: A viscosity measuring apparatus comprising a removable viscosity testing module and a viscosity testing apparatus. The removable viscosity testing module comprises a ducting arrangement having a first portion for receiving the fluid and a second portion fluidly connected to the first portion. The viscosity testing apparatus further comprises means for causing the fluid to pass along the ducting arrangement between the first and second portions. The ducting arrangement comprises a first reference point, and a second reference point disposed downstream of the first reference point, the first and second reference points being separated by a fixed, calibrated distance along the ducting arrangement. The apparatus further comprises detecting means for detecting when the fluid reaches at least one of the first and second reference points, and a timer for determining the time taken for the fluid to pass from the first reference point to the second reference point.

    Abstract: A system and method for measuring the deformation over time of the surface of a non-Newtonian fluid in a sampling container in response to an airjet that is applied for a specified time. The change is the sample surface displacement is measured quantitatively by means of optical triangulation or other similar optical or electronic distance measuring device. After cessation of the airjet, gravitational forces cause the sample material to flow back to its original surface profile. Both the amplitude of the deformation displacement due to the force of the airjet and the recovered displacement, within specific time periods are characteristic of asphalt binder material with varying amounts of polymer or other additives used to control the ultimate properties and performance of the material. As a result, comparison of the quantitative measurements of control samples can allow discrimination from samples with different properties and hence different formulations.
